Application filed Febn ary 20, 1907. Serial No. 358,518.

; Be it known-"that 1, JOHN. R. KLINE, a citizen of the United States,residing at Los 'Angeles, in the county of Los Angeles and "State ofCalifornia, have invented a new and useful -.Pneumatic Tire for Vehicle-.Wheels, of which the following is a specification.

This invention is particularly intended Q ;'for. application to;automobile wheel tires 1 and particularly to such tires as comprise anouter tube and an inner tubular means, and

the main object of the invention is to so, construct the inner tubularmeans that any puncture or injury in any part of the tubular means willnot affect the general elasticity of the tire.) a

lbject of the invention is to facilitate the location or finding of anydefect or puncture in the tire.

The; inventiomcornprises an inner tubular I means-made upof cellsorsections, each of whichfi's inflated so that esca e of air from any onesection does riot a ect the other 1 sections, and 1n this connection anob ect of the invention is to provide for inflation of all the sectionssimultaneously, so that inflation of such a tire can be accomplishedasreadily and quickly as an prdinary continuous inner tube. In thisconnection the invention also "provides means'for releasing the pressurein the several sections of the tire.

- In the accompanying drawings :-Figure 1 is a side elevation, partly insection, ofthe tire.' Fig. 2 .'is a transverse section on line m Fig. 1.Fig. 3 is a transverse section on the line av -i13 in Fig. 1

Fig. 4 is a view similartoFig. 2 -show1ng the pressure releasing meansinserted.

1 designates the outer tube which'rnay be of any usual or suitableconstruction, and 2 designates the rim'of the wheel which is pro videdwith usual means 3 for engaging and holding'said outer tube. Said'o'utertube has the usual annular slot 0 opening on the inside thereof,so that. the inner tubular means can rest directly against the said rim.The inner tubular means consists of a plurality of sections or cells 4,each of such sizeand shape as toffill an arc of the outer tube, each,cell, being closed .at each end "and the cells'being placed end to endwith: in the outer; tube; The cells are preferablymade "Lsott vulcanizedrubberQ Valve means ar provided for charging each cell with compressedair; For this purpose each cell has an opening 5 on its inner face .tore- .press firmly against one another.

- ceive and fit tightly around an inlet valve 6 which may be anysuitable form of check valve.'and. which communicates with adistributing tube 7 extending around the rim and within the series ofcells. It is preferred to indent or groove the cells on the inner facesto receive this distributing tube.

8 designates a valve for so plying air to the distributing tube, saidvalve being any suitable form of check valve and having the usual screwcap safety closure 9 for closing the same when not in use. Check valve 8opens inwardly in the usual manner of valves for charging pneumatictires and the valve 6 of each cell opens inwardly into that cell so asto allow air to flow into the cell but not to flow back into thedistributing tube. Each cell or. section 4 is further provided with apressure release valve 10 which opens inwardly. These release valves areplaced opposite openings 11 in the rim to enable the'valves to be openedand to permit pas-- sage of the air in the valves as hereinafter setforth.

. The valves 6 and 10 may be of any suitable construction but arepreferably of the simple form shown, made by extending a part of theWall'of the valved member; for example, by extending a part of the wallof the cell or section in the form of a tube, as shown in .Fig. 3, andbringing the two sides of said 0 en in a given direction and will remaintightly closed against pressure in the other direction. r

. In inflating the wheel the cap 9 is removed,-

any usual pneumatic supply means is connected to the valve 8 andcompressed air.

forced into the distributing tube 7, whence it passes through the valves6 into all the cells .of the tire, inflating the same and causing.

said cells to press firmly against the "outer tube, and causing the endsof the cells to In case of a puncture in any section the air will escapetherefrom but will not affect the other sections'which will still retaintheir elasticity,

' and by making the sections sufficientl Y short it is ossible to thusobtain a tire whic is not ren ered inoperative by a single puncture, butcan-be used temporarily until-it is possible toremove or repair thetire.

In repairing the tire the sectional conpenetrating the release'va vesand permit-v struction is an advantage in the first place in enablingthe location of the puncture to be determined immediately by mereinspection, and in the second place if the puncture is so severe as topermanently injure the rubber or to prevent effective repair of therubber, the injured cell may be discarded and replaced by a perfectonewith slight expense.

When it is desired to remove the tlre for repairs, it is necessary torelease the pressure therein, as such ressure holds the tire tightly inplace anrlprevents removal. Be fore removing thetire, a suitable toolsuch as a tube of sufficiently small diameter is in' serted through theopenin s 11 in the rim,

ting the air to flow through the-tube so as to discharge or release thecompressed air in the section or cell.

Y This operation may be quickly performed in all thetubes. If desired,however, separate charging valves may be used for the separate sectionsor cells and said charging valves may beused-also to discharge the cellsvalve.

What I claim is I ll A pneumatic tire comprising an outer tube and innertubular means having a plurality of-isections formed as elastic cellsplaced end to end, each cell forming a pneumatic chamber, and means forinflating all-of by pressing in the ball of the said cells'simultaneously-'comprismg a d'istributing tubehaving an inwardly openingcheck valve, a check valve openin inwardly Y 2'.
